U.S. Pat. No. 6,216,997 B1 discloses a Christmas tree stand which includes a base and a clamping mechanism which has a pair of opposed jaws to clamp the tree.

Christmas trees are popular. Difficulty in orienting and maintaining the trees in a vertical position is a common problem. Since the trees often bear lights and sometimes even candles, it is imperative that the Christmas trees remain upright in their stands so as to minimize fire risk and also to minimize damage to the tree, decorations on the tree, and surrounding furniture, flooring and woodwork. The problem is exacerbated by the desire to have a larger (taller and wider) Christmas tree.

It is, therefore, desirable to have a device and a method of ensuring that a Christmas tree regardless of size and straightness of the trunk, be securely mounted in an upright position.

It is also desirable to have a device and method of ensuring that a sapling or other young tree is supported to enable growth until replanting can be effected or until the support is no longer necessary for the growth of the tree.

DESCRIPTION OF THE INVENTION

FIG. 1 is a perspective view 100 of a prior art Christmas tree stand. Most prior art Christmas tree stands employ a plurality of threaded screws 104, 117, 120, 124 having handles 103, 116, 119 and 123 for rotating the screws thus positioning the screws radially inwardly or outwardly. Each of the screws 104, 117, 120, 124 have threads which coact with reciprocal threads 102, 118, 121, 125 in a circumferential support 101 which is part of a container or bowl 130 capable of holding water to feed the tree placed therein. Reference numeral 105 indicates the interior hollow cavity of the bowl 130.

Screws 104, 117, 120, 124 are oriented radially with respect to generally circumferential support 101. Each screw 104, 117, 120 and 124 has a respective end 127, 128, 129 and 126 for engagement with the tree. The ends of the screws have limited diametrical area and, as such, do not support the tree very well. Since, the screws have limited diametrical area they protrude into the tree differently depending on whether a soft spot of the wood is engaged. In a similar fashion, hard spots of the wood do not allow penetration of the screw. Therefore, a user is left with an uneven at best gripping of the tree by the screws. The grips of the instant invention greatly enlarge the surface area which engages the tree. Further, the grips of the instant invention also included serrations and/or protrusions which engage the tree. The grips of the instant invention provide secure engagement of the tree from four positions. It is desirable to use four grips of the instant invention but two grips spaced 180 degrees apart may be used.

Bowl 130 is mounted atop plate 107 and is supported by leg pairs 112, 113; 111, 114; 109, 106; and 110, 115.

FIG. 2 is a perspective view 200 of the Christmas tree stand of FIG. 1 in combination with a plurality of tree grips 201, 202, 203 and 204 of the instant invention. Each of the tree grips 201, 202, 203 and 204 include a first surface having serrations 205, 206 and 207 thereon as viewed in FIG. 2. Screw 117 is illustrated extending into bore 208 of the second oppositely oriented surface. FIG. 3 is a perspective view 300 of the Christmas tree stand of FIG. 1 in combination with the tree grips 201, 202, 203 of the instant invention and a portion of a tree 301.

FIG. 4 is a partial cross-sectional view 400 taken along the lines 4-4 of FIG. 3 illustrating tree grips 201 and 203 in cross-section. Preferably the tree grips are manufactured from Aluminum but they may be constructed from steel, wood, polyurethane, nylon, acrylic or any other rigid polymer. Referring still to FIG. 4, threads 104, 120 are received and restrained by respective reciprocal threads 102, 121 which maintain the screws (threaded members) in position relative to the circumferential support 101. Reference numerals 302, 303 indicate compression and deformation of the wood of the tree 301 by serrations 205, 206 of the tree grips 201, 203. Spike 401, part of the prior art tree stand illustrated in FIG. 1, also penetrates wood 301 and stabilizes the tree from the bottom.

Bores 304, 305 in the second surface of tree grips 201, 203 are illustrated in FIG. 4. Ends 127, 129 of the screws are illustrated engaging the respective bores 304, 305 which urge tree grips 201, 203 into compression with the tree 301. This causes the serrations or protrusions to cut into and deform the wood fo the tree 301.

FIG. 4A is an enlargement 400A of a portion of FIG. 4. FIG. 4A illustrates the compression of the wood 301 by serrations 205 of the grip 201. Still referring to FIG. 4A, screw threads 104 interengage reciprocal threads 102 in the outer circumferential support 101. Screw member 104 includes end 127 which engages the bottom of bore 303 which pushes the tree grip 201 leftwardly as screw member 104 is rotated by handle 103. Tree grips 201, 202, 203 and 204 apply pressure to a relatively large surface area of the wooden tree. Additionally, the grips frictionally engage the tree by virtue of the serrations and/or protrusions on the second surface of the tree grip.

The tree grips illustrated in FIGS. 2-4A are illustrated in more detail in FIGS. 5-11. Preferably, the tree grips are 3 inches long, {fraction (3/4)} inch wide and {fraction (3/4)} inch high. The length is sometimes referred to herein as the longitudinal direction and the grip has a longitudinal axis running therethrough. FIG. 5 is a top view of the first embodiment 500 of the tree grip 201, for instance. When referring to FIG. 5, the longitudinal axis (vertical axis) runs vertically through the center of mass of the tree grip. The horizontal axis runs transversely through the tree grip through the center of mass. Reference numeral 501 represents a peak of one of the serrations 504 and reference numeral 502 represents a valley of one of the serrations. Another one of the serrations 503 is illustrated in FIG. 5. FIG. 6 is a right side view 600 of the first embodiment of the tree grip. FIG. 7 is a front view 700 of the first embodiment of the tree grip. FIG. 8 is a left side view 800 of the first embodiment of the tree grip.

FIG. 9 is a bottom view 900 of the first embodiment of the tree grip illustrating the second surface 901 and a bore 902 therein. Referring to FIGS. 4A and 9, the bore of the tree grip is offset from center approximately {fraction (1/4)} inch and is biased toward the upward end 504 of the tree grip. The bore as shown is approximately {fraction (7/16)} inch diameter and is approximately {fraction (3/8)} inch deep. The bore is vertically offset approximately {fraction (1/4)} inch. The serrations are arranged in a transverse relationship and, when viewed from the side, the base of the triangle is {fraction (1/4)} inch and the height is {fraction (1/8)} inch. While this position of the bore and this size of tree grip is disclosed in detail herein, other positions of the bore and other sizes of the tree grip are specifically contemplated. For instance, the tree grip may have different dimensions as the situation requires. It may be taller, wider and higher and may have a bore placed in a different position. For some applications an extremely lengthy (extremely long) tree grip may be used. FIG. 10 is a rear view 1000 of the first embodiment of the tree grip.
